Tenneco announced that it is supplying key emissions control technologies on the 2014 Ram Heavy Duty diesel truck series, which includes the 2500 and 3500 Heavy Duty diesel pickups and the 3500, 4500 and 5500 chassis cab trucks. Tenneco supplies aftertreatment components, including the diesel oxidation catalyst, diesel particulate filter and selective catalytic reduction (SCR) system on the full truck line.

Tenneco has supplied the SCR aftertreatment system on the Ram chassis cab truck series since 2010 for both previous and current-generation designs. The Ram Heavy Duty diesel pickup trucks added the SCR technology for the first time when production of the redesigned 2500 and 3500 series trucks began last year at Chrysler’s Saltillo, Mexico Truck Assembly Plant.

Tenneco produces the aftertreatment components at its manufacturing facilities in Smithville, Tennessee and Puebla, Mexico. Engineering and development was conducted at the company’s global emissions control technical center in Grass Lake, Mich.
